16 HETEROMERA. 
the base; elytra rather long, convex, a little rounded at the sides, about the width of the thorax, with 
rows of very fine punctures distinct to the apex, the interstices with scattered finer punctures ; legs and 
antenne red. Beneath coarsely punctured, metasternum long, intercoxal process pointed in front. 
Length 63-7 millim. 
Hab. Mexico, Puebla (Sallé), Tehuacan (Hége). 
Three examples. Of the form of some of the winged species (E. longulus, &c.) ; 
narrower and longer than any of the apterous species known to me. 
21. Emmenastus glabratus. (Tab. I. fig. 8.) 
Apterous, oblong ovate, convex, black, shining. Head coarsely and closely punctured; prothorax transverse, 
moderately convex, widest behind, narrowed in front, anterior angles obtuse and a little prominent, hind 
angles obtuse, the base nearly straight, closely evenly and rather coarsely punctured, the punctures a 
little confluent at the sides; elytra convex, a little wider than the thorax at the base, with regular rows 
of coarse punctures distinct to the apex, the interstices finely and sparingly punctured; legs and antennz 
reddish brown. 
Length 7-8 millim. 
Hab. Mexico (coll. F. Bates), Tehuacan, Oaxaca (Hége). 
Taken in numbers by Hoge at Tehuacan: Larger, broader, and not so closely punc- 
tured as E. obesus, Lec., from New Mexico &c., the punctures of the elytral stricee much 
coarser. 
22. Emmenastus curtus. 
Apterous, ovate, very convex, black, rather dull. Head very closely and coarsely punctured ; prothorax trans- 
verse, strongly convex, rounded at the sides, widest just before the base, narrowed in front, the angles 
obtuse, base nearly straight, very closely regularly and rather coarsely punctured, the punctures a little 
confluent at the sides, feebly impressed transversely before the base; elytra a little wider than the thorax 
at the base, very convex, rounded at the sides, somewhat closely regularly and coarsely punctured, with 
rows of scarcely coarser punctures, distinct at the sides, obsolete towards the suture and not reaching the 
apex. Beneath shining, coarsely punctured; intercoxal process pointed in front. Legs and antenne 
reddish brown. 
Length 5-6} millim. 
Hab. Mexico (coll. F. Bates), Tehuacan (Hoge). 
Taken in some numbers by Hoge. This species is comparatively shorter, broader, 
and more convex than any of the apterous species here described. The thorax is very 
closely and evenly, and almost confluently punctured. 
23. Emmenastus lentus. 
Apterous, oblong ovate, convex, dark reddish brown, shining. Head reddish brown, coarsely and closely 
punctured, rugulose; prothorax reddish brown, convex, transverse, widest just before the base, a little 
narrowed behind, narrowed in front, but little rounded at the sides, the anterior and posterior angles 
obtuse, the base straight, closely regularly and somewhat finely punctured, the punctures confluent at 
the sides; elytra convex, a little wider than the thorax at the base, slightly rounded at the sides,
